What are the problems to be solved in the recycling of lithium batteries?

What problems should lithium battery recycling solve? Since its inception, lithium batteries have quickly occupied the battery industry with their excellent performance and have been used in many industries. It became popular in mobile phones in 2000, and gradually occupied the 3C consumer digital product market. Lithium batteries are so widely used, but there is not much significance in recalling them. After use, it is mostly treated as ordinary garbage. This caused serious pollution. The following professional lithium battery processing manufacturers-technical personnel analyze for us that the cathode materials of lithium batteries are mostly metal oxides with lithium transitions. Among them, the most widely used is LiCoO2, which is also the earliest commercial cathode material for lithium ion secondary batteries. In addition, with the development of anode materials for lithium batteries, LiCoO2 is mixed with a small amount of nickel and its mixed oxides (licoxni1-xo2, 0). The most important recovery is the use of acid leaching and solvent extraction phase hydrometallurgical technology, followed by the use of electrochemical technology to accumulate metals in the leaching solution and directly correct the failed electrode materials. Metallurgical skills are now important metal recovery skills used in lithium batteries. Therefore, its recycling is also continuously promoted with the development of metallurgical technology, and the development of microbial metallurgical technology is the most complicated. Currently, this technology cannot be used for lithium battery recalls. As people's requirements for the environment are getting higher and higher, the recall of lithium batteries is bound to be widely used. In the future, the recovery of lithium batteries, in addition to recovering useful resources, materials that must be properly handled can have an adverse impact on the environment, and according to the development of lithium batteries and future environmental needs, the future lithium battery treatment will be sensitive and diversified. Direction. Power lithium battery is a kind of lithium battery that can be charged and discharged with high current. For electric vehicles, power tools, portable electronic equipment supporting power supply and power lead-acid batteries: small size, light weight, long service life, clean and environmentally friendly and many other advantages, has been widely used. Compared with other batteries such as lead-acid batteries, lithium batteries have the following characteristics: 1. Long life, 3-5 times that of general lead-acid batteries, and can charge and discharge 2000 times. 2. Light weight, generally 4-5 pieces of lead-acid battery, such as 48v-12ah lithium battery weighs only 4 kilograms, lead-acid battery weighs about 17 kilograms. 3. Its size is very small, only one-third the size of a general lead-acid battery, such as a 48v-12ah lithium battery, which is only as big as a cigarette stick. 4. There is no pollution to the environment and no heavy metal pollution. 5. Safer, no acid outflow, no corrosion, circuit protection will not be overcharged or over-discharged. 6. No maintenance required. Lead-acid batteries should be refilled with electrolyte and distilled water regularly. 7. Good performance and low self-discharge rate.
